Textbook Question

Chapter 10.13, Problem 17P

Which will occur at a larger wavenumber:

a. the C 8 O stretch of phenol or the C 8 O stretch of cyclohexanol?
b. the C 9 O stretch of a ketone or the C 9 O stretch of an amide?
c. The C 8 N stretch of cyclohexylamine or the C 8 N stretch aniline?

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
